Keep In Mind
The Inca Empire had no writing system, but instead recorded information with knotted strings called quipu.

When the Spanish conquistadors (and their Amerindian allies who made up most of their troops) destroyed the Inca Empire, they destroyed many of the quipu strings, which means that much of our knowledge about Andean mythology comes from Spanish chroniclers as well as Andean Native informants in the post-conquest Encomienda era (1600s-1800s).
One such text is the Huarochiri Manuscript, or "A Narrative of the Errors, False Gods, and Other Superstitions and Diabolical Rites of the Indians"
You can tell that it was the "more enlightened" Christian priests who were writing this down.

Accounts like this must be taken with a grain of salt
(or a bundle of llama wool)


The Andes region is still predominantly Amerindian by ethnicity today.

Also, saying "Ancient Inca" is misleading because (Fun Fact)
Cambridge University is older than the Inca Empire!
Cambridge University was founded in 1209.
The Inca Empire started in 1438.

Before that, there were earlier civilizations in the Andes such as the Moche, the Chavin, the Tiwanaku, and the Nazca [known for the Nazca lines, which (Shock Horror) were not made by space aliens].
